Central ventilation units AIR1 XVP
b Outdoor Compensated Supply Air Control
The supply air temperature setpoint can be set to improve the regulation of room heat losses due to the outdoor tem-
perature. This ensures that the cooling of room walls is compensated for during the cold season.
The supply air temperature setpoint is compensated for depending on the outdoor temperature using a control curve
with 8 points.
Example:
Outdoor temp [°C]
Supply air temp [°C]
-20
-15
-10
-5

Temp. control mode
Outdoor comp supply
Outdoor comp setp.
-20.0 °C = 25.0 °C
-15.0 °C = 24.0 °C
-10.0 °C = 23.0 °C
Outdoor comp setp.
-5.0 °C = 23.0 °C
-0.0 °C = 22.0 °C
-5.0 °C = 22.0 °C
Outdoor comp setp.
10.0 °C = 18.0 °C
15.0 °C = 18.0 °C
c Cascade Room Temperature Control
Only possible with the humidity-temp. sensor AIR1/KWL-FTF 0-10V accessory.
Connect the analogue output A2 (temp. signal) of the AIR1/KWL-FTF 0-10V to the analogue input AI2 of the ventilation
unit (see wiring diagram).
The cascade control of the room and supply air temperature is used to maintain a constant, adjustable room tempe-
rature. The supply air temperature setpoint is set by the room temperature controller according to the deviation of the
ambient temperature from the room temperature setpoint.
The room temperature setpoint is displayed in the "temperature" menu (log in as User or Admin):
Temp. control mode

Min: XX.X °C
d Cascade Extract Air Temperature Control
The cascade control of the extract air and supply air temperature is used to maintain a constant, adjustable room tem-
perature. The extract air temperature controller output signal influences the supply air temperature controller setpoint.
The setpoint is displayed in the "temperature" menu (log in as User or Admin):
